ugh, i dont really like whispers, they are big, bulky, dont circulate water well (water from the outake just goes right back in), and the cascade straight down makes it impossible to put stems underneath to hide them. i know they are cheap, but there is a reason for it. too late now, but i suggest you switch out in a year or so for an ehiem ecco (thats what i have and i LOVE it).

how will you diffuse the other bottle? (if you can do it, you will have the perfect amount of CO2).

you lighting is kinda low. less then 2 watts per gallon. i know its T5 but still. its all preference but i preffer yellows and reds with immense lighting.

two thumbs up for the flourite (two thumbs down for rinsing it, it takes forever).
